Embodiment Construction

[0067] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0068] combine figure 1 As shown, the digital camouflage pattern generation method based on image fractal texture comprises the following steps:

[0069] s1. Extract the background main color of the background image and the area ratio of the background main color

[0070] In the embodiment of the present invention, based on the layer-by-layer K-means clustering algorithm of the pyramid structure, the background main color of the background image and the area ratio of the background main color are extracted, and the general steps are as follows:

[0071] s1.1, color space conversion

[0072] The Lab color space is a uniform color space with a wider color gamut than RGB and more colors that can be represented, so the background image is converted to the Lab color space;

[0073] s1.2, downsampling Gaussian pyramid model

[0074] The down-sampl...

Abstract

The invention discloses a digital camouflage pattern generation method based on image fractal texture, which comprises the following steps: s1. extracting the background main color of the background image and the area ratio of the background main color; s2. generating based on the improved fractal Brownian motion Texture image; s3. Coloring the texture image; s4. Enlarging the initial camouflage pattern image according to the unit size; s5. Converting the enlarged camouflage pattern image into a camouflage vector image. The present invention introduces standard deviation correction in step s2 to prevent the generated texture image from being too discrete, improves the coloring method in step s3, that is, uses a mixed coloring algorithm to color the texture image, and in step s5 Vectorize the image so that the camouflage pattern is scale-invariant. The invention can design a camouflage pattern with strong randomness, adaptability and camouflage effect by solidifying the texture image generation step, optimizing the texture pattern generation algorithm and improving the coloring algorithm.

Description

technical field [0001] The invention belongs to the technical field of image processing and analysis and camouflage camouflage design, in particular to a digital camouflage pattern generation method based on image fractal texture. Background technique [0002] Digital camouflage is a new generation of camouflage camouflage that comprehensively uses advanced technical means. It is based on the characteristics of human's visual psychological perception of graphics, the characteristics of digital imaging dot matrix, and the characteristics of human vision for target recognition. presented in the form. [0003] The current main methods of camouflage design are divided into manual work and computer intelligent design, among which: [0004] Manual work is that designers design camouflage patterns in drawings or computer-aided design software based on personal experience. This method has the disadvantages of time-consuming, low efficiency, and similar designs. At the same time, i...
